About this map

The Sierrita Mountains and Coyote Mountains dominate this 1940 topographic landscape, revealing a high-desert environment defined by mining prospects and isolated ranching outposts. Numerous mining operations appear in an inactive state at the time of the survey, including the Copper Glantz Mine, Aguinaldo Mine, and Johnny Mine, signaling a shift in the local economy away from the extraction of earlier decades.
